in a certain country, that the proportions of" no change audits" (that is audits that uncover no additional taxes are due) has risen over the years and currently approximately .26. Suppose that a random sample is taken of 100 audits.

A) What is the probability that the sample has between 24% and 27% no-change audits?

B) What is the probability that the sample has between 20% and 30% no- change audits?

C) What is the probability that the sample has more than 30% no-change audits?
